Modes of Operation: CFB Mode
Learn about the cipher feedback mode of operation, the one in which a series of bits are encrypted as a single unit or block.
Cipher feedback mode
An alternative way of providing message dependency is to use cipher feedback (CFB) mode. CFB mode has broadly similar properties to CBC mode but is subtly different in its operation.
Encryption using CFB mode
There are several variants of CFB mode. The basic version of CFB mode encryption is illustrated in the below:
